Connection torque of D38999 circular connectors?
(OP)
Long time lurker, but apparently this is my first post! I'm a mechanical guy so I apologize in advance for any stupid questions :)
I'm wiring a show car (hobby, not professionally). I just received a bunch of MIL-DTL-38999 Series III connectors I purchased. I've used the bayonet style connectors, but this is my first time using the threaded Series III connectors. It seems when the EMI grounding fingers engage it gets much much harder to turn while mating. Is this normal? I know that's a bit vague... I don't know how/who else to ask.
The manufacturer of these connectors is Deutsch. Is it a quality issue? They were about half the cost of equivalent ITT Cannon or Amphenol.
Here is a picture of the connectors:

The connectors are mated when red band on the side of the bulkhead connector is covered by the mating connector.

I am connecting without pins or sockets, but you can feel the shell threads tighten up far before it gets close to the red band. Both connectors have the same keyway rotation (Normal) and both are electroless nickel plated.
It might just be that you can't learn "feel" from a catalog and I'm being paranoid, I will try again this evening. Thanks for your replies!
